Cathedral Edge: Photoevaporation at Carina’s Pillar Foot I positioned the observer inside a shadowed alcove at the base of a 3-parsec molecular column (dust at ~40 K), looking outward toward a knot of O-type stars (surface ~40,000 K) backlighting the eroding skin. Here we witness ultraviolet flux carving scalloped ionization fronts, H-alpha streamers bleeding sideways, proplyd tails unfurling, and a jagged shock arc glowing in saturated magenta and turquoise from argon lines—an anomalous flare against the familiar gold and teal. This frame captures the decisive tension of starbirth: protostars (1–10 L☉) whisper from within while radiation and stellar winds unmake their cradle in real time, the scale stretching from sub-AU proplyds to parsec-high pillars in one breathless vista.
